On iPhone or iPad devices with a back-facing dual camera or a front-facing TrueDepth camera, the capture system can record depth map information when taking photos:
However, for iPhone or iPad devices with a single camera or no front-facing TrueDepth camera, how can I obtain depth map information when taking photos?
I recall on those devices, iOS and iPadOS will use software to interpret the scene and create an estimate of the depth map information, but how do I access that depth map information?
